I was driving on the highway at about 65 miles per hour. I went to accelerate and heard and felt a loud boom. The car shuttered and smoke began to pour into the car. I slowed down and pulled over to the right shoulder of the freeway. I cut the car off and couldn't restart it. The bay area freeway service patrol stopped to tow me to a safe area. The technician said there was oil all over the road and back of the car. Car was towed to the nearest Ford dealership. The inspection found a cracked engine block. The car has 74,000 miles on it and Ford is unwilling to help because there was no warranty on the vehicle.

Today I was driving my 2015 Ford Mustang when suddenly the car began to lose speed. The car was slowing down and wouldn't let me accelerate. Eventually while wanting to check if my car was okay I tried to make a left turn into a parking lot and the car engine shut off but the lights and everything were still on. I had to wait awhile and eventually I was able to turn the car back on and safely move into a walmart parking lot.

2015 Ford Mustang has a carbon monoxide leak in the cabin when A/C is on. Recorded carbon monoxide readings of 28 ppm and 17 ppm one week apart using a digital detector. Tested multiple other family cars with same detector under same conditions and received readings of 0 ppm, indicating detector is working accurately. Car originally had cracked exhaust and strong fumes that leaked into cabin with A/C on. Car was brought into service department and exhaust/catalytic converter were replaced. Carbon monoxide continued to leak into the car interior after repair, and contact experienced headaches, near loss of consciousness, dizziness, fatigue, and chest pain. Multiple medical visits were made for the experienced symptoms. Car was brought back to service department and exceeded the reasonable repair wait time after staying 34 days at dealership service department for repair.

Mustang

  • 500 miles
I have a 17 Mustang GT with manual within the first 1000 miles the engine has automatically turned it self off after getting on a interstate or any time extra power is needed. I would want to stop speeding up I would push the clutch in and put it in 6th and wait for my mph drop to desire speed, during this time is when the engine turns off. I have went to a Ford dealership in richmond, va and they basically said they can't find any issues because their are no codes (the car didn't leave the property). So this issue is a hard to find a fix and most likely won't get fixed till people start getting in accidents or death by accident because of the unpredictable engine shut off.

Rodents have been chewing on the wiring under the hood. I feel this is due to the soybased wiring coating that is being used on newer vehicles. 1st incident. The ac wiring was effected. 2nd incident 2 weeks later engine wires were chewed up. This seems very similar to the current Honda rodent issues that a class action lawsuit is currently filed for. The vehicle was parked under my carport over night. It is a daily driver used everyday.

Purchased 2015 Mustang 5.0 with only 6000 miles. And numerous times I tried to register my Mustang with Ford sync vehicle health report but said my vehicle wasn't compatible, which I didn't understand. When I hit 13000miles... I noticed vehicle ac was not cooling for a couple days. I made an appointment with dealership but day before I was driving on the freeway checking if maybe the ac would work all of a sudden, the engine shut off.... I pushed the clutch back in and started it as I was in neutral. Engine turned back on and I turned off the radio and ac. Thank god I made it back home.

Mustang

  • 8,000 miles
Purchased the car brand new Nov 2014. The 1st occurrence was around may or June of 2015 on a city street and I was slowing down while in 6th gear with the clutch pushed in and then I pulled the shifter into neutral. The run active power caught my eye and then there I also so the the RPM was on 0. I questioned myself on this 1st incident that maybe I did something wrong. 2nd incident happened sometime in Sept 2015 and I was on another city street in 4th gear getting ready to come to a stop at a red light, with the clutch all the way to the floor I placed the shifter in neutral and I had a feeling that the car wasn't on anymore and looked at the gauges and saw that run active power was on again and RPM was on 0. this time I kind of started to suspect the car. 3rd occurrence happened June 11th 2016 and I was on a highway slowing down from 55 or so and push in the clutch to neutral and while rolling in neutral around 40 to 45 mph I saw the RPM go straight to 0 and at this point im convinced there needs to be a recall. All 3 incidents I quickly started the car back up while rolling. Also since I've purchased the car I've had the display randomly say that all of my drive modes are unavailable, traction control unavailable, hill assist unavailable, and a few more. 1st time I noticed that was while sitting in traffic, and 2nd time was on a random start up. I believe this could be a computer issue. VIN number unavailable updated 6/15/18

My engine has randomly shut off three separate times now. I have about 12,000 miles on mt 2015 Mustang GT w/pp manual transmission. The first time I was parked and it was idling, my friend and I both witnessed the idle dip, then 3-5 seconds later the engine shut off. The second time (was much more dangerous) I was changing lanes because of a car fast approaching from behind, I downshifted from 3rd to 2nd gear (30-40mph), let out the clutch smoothly, pressed the accelerator and the car did nothing, I looked down and the RPM was at 0 and "press clutch to start" was displayed on the gauge cluster screen. I quickly depressed clutch and restarted engine and took off to avoid an accident. The third time happened today 3/15/2016 I was again at idle and the engine just shut down without me touching anything, it again displayed "press clutch to start". I've read in forums that many people are having this issue intermittently, this could be a serious safety issue that can have deadly consequences. Please address this issue correctly rather than sending everyone home with the "we didn't find any issue" go-to response. Hopefully people don't have to get injured, or god forbid die, before this issue is taken seriously.

Mustang

  • 80 miles
Car is experiencing a vibration problem at 65 to 75 mph, in 6 gear, and engine is at 1750 RPM. Vibration is duplicated again, in 5th gear, and engine is at 2500 RPM. Also, with car in the stop position, car in neutral, with clutch in or out, slowly revving the engine vibration occurs at 1500 to 1750 rpms. Also if you quickly rev the engine to 2500 RPM and drop revs slowly vibration reoccurs at 1750 to 1500 RPM. This problem has been present with initial purchase of vehicle, dealership said it was tires and drive it for awhile. The car has since been in the dealership 5 times, replaced all 4 tires, force road balanced 3 times, and has been to second Ford dealership for confirming vibration problem. Second dealership also had another new Mustang experiencing same vibration and could not be fixed. Ford Motor Company has declared the vibration problem is within specs for Mustangs and has declared it "normal operating characteristics" for Mustangs. At this point my case with Ford has been closed. If this vibration problem is occurring in 40 percent of Mustangs as a prior complaint has stated then Ford motors need to address it and not ignore it.

Mustang

  • 1,900 miles
Vehicle event while driving on the highway. While adjusting the air temp with my right hand, my pinky touched the start stop button causing the vehicle engine to shut down. I pulled to the side of the road to figure out what had happened and discovered that my car would shut down in drive by just touching the start stop button. The only way to restart the engine is to put the vehicle in park. It was safe for me, although I was in a line of traffic, because I was on a two lane road with shoulder room available. The seat did not return to the exit position. I am very careful now when making any adjustments to the controls cluster because of the closeness of the start stop button to the other controls. The switch also operates with very light pressure and its surface is convex. I do not let anyone else drive this vehicle in its current condition.
